If the Focusrite Control software is showing you low input levels, that is nothing to do with PowerTracks or any other software at all, it would most likely be a problem with the keyboard, the wiring, or the audio interface itself.

Either way, to use the rear inputs for recording, please go to Options > Preferences > Audio, make sure Audio Driver Type is set to ASIO, then click Drivers. Select "Input 3 + Input 4" on the left side under Input Ports, then click OK.
